“…The second relationship concerns the compatibility between names and data associated to some operation oexp ∈ Oexp in the expected WS and those associated to some operation o act ∈ Oact in the actual WS. For the sake of simplicity, here we assume that states and operation names and data are compatible if they are called the same way (more sophisticated compatibility relationships can be identified by assuming the existence of a semantic network of concepts as in [9]). Given these definitions, we say that, given a sequence of operations in the automaton of the expected WS, this can be substitutable by another sequence of operations in the automaton of the actual WS if the following conditions hold:…”

“…In order to complete our translation we map each of GetLyric inputs on an univocal label and we do the same for each of getSong inputs, so, for instance, both id (input of getSong) and GetLyric_lyricId (input of GetLyric), which represent the id of a song, are mapped on the label lyricId. This translation step is carried on exploiting ontology-based reasoning, which we do not describe into details here, but can be found in our previous work [9]. The compatibility relations for input and return parameters of the example expected and actual services are reported respectively in Table 1 and Table 2.…”

“…Many approaches that support the automatic generation of adapters (or equivalent mechanisms) are based on the use of ontologies and focus on non-conversational services (see for instance our previous work [9] and [11]). They all assume that the usual WSDL definition of a service interface is enriched with some kinds of ontological annotations.…”

Service-oriented applications are typically built out of existing web-services (WSs) possibly made available by third party vendors. This requires that the application has to be able to evolve when the composing WSs are not anymore available or when new, more useful ones, are published. In this setting, an important problem is to understand how to use WSs showing an interface that differs from the one the application has been built to. The problem becomes even more complex when we consider conversational WSs, i.e., WSs that expose operations that have Input/Output (I/O) data dependencies among them. This paper presents a complete development methodology to the automatic synthesis of adapters for conversational WSs starting from their WSDL interface. The result is a tool-supported methodology that takes as input the WSDL of a pair of services and automatically builds a script that maps a sequence of operation invocations on a "WS to be replaced" into an equivalent sequence of operation invocations on the "replacing WS". The overall approach is presented by applying it to two existing WSs that realize two distinct, but equivalent, search engines for lyric music.

“…Previous studies have extensively investigated how to set up interface mappings for two services [2,3,7], which therefore, will not be our focus in this paper. Assuming the interface mappings have been defined, we will only concentrate on how an adaptation contract can be generated for a given abstract operation sequence.…”

“…Adaptation is a promising technique to overcome such mismatches in a non-intrusive way [2][3][4][5][6]. With the help of an adaptor, the abstract service invocations are adapted to their concrete implementations, making the resulting substitution satisfy the expectation of the composition properly.…”

Dynamic substitution of conversational services during the execution of service orchestrations is a challenging issue in Service-Oriented Architecture. For a conversational service and its candidate substitute service, there may exist mismatches at interface level as well as protocol level. To make the service substitution consistent, it is essential to implement adaptation to overcome both types of mismatches. In this paper, we present an automatic approach to generate adaptation contract for conversational service substitution. Our approach is based on graph planning technique, which enables us to retrieve a solution in polynomial time. Experiments show that the proposed approach is potentially applicable for on-the-fly service substitution.

In Service Oriented Architectures (SOAs) services invoked in a com-\ud position can be replaced by other services, which are possibly discovered and\ud bound at runtime. Most of the research efforts supporting this replacement as-\ud sume that the interface of the interchangeable services are the same and known\ud at design time. Such assumption is not realistic since it implies that providers of\ud the same kinds of services agree on the interfaces the services offer. By interface\ud mapping we mean the class of approaches aiming at relaxing this assumption.\ud Most of those approaches available in the literature focus on stateless services and\ud simply address mapping operation names and data structures. Instead, this paper\ud focuses on conversational services for which the sequence of required operation\ud calls, i.e., the interaction protocol, matters. We use model checking to automati-\ud cally identify the interaction protocols mapping. We validate our technique both\ud by applying it to the invocation of two real services (Flickr and Picasa), and by\ud quantitatively comparing it to a related approach
